Principal Eigenvalues and Perturbation,In a classical article, Hess and Kato study the problem . where . is a strongly elliptic operator on a bounded open set Ω of .. with Dirichlet boundary conditions and . is a continuous bounded function on Ω. They show that there exists a unique λ > 0 such that the problem (0.1) has a solution.
